With the foregoing and other objects in View this invention consists insuch novel features of construction combination and arrangement of partsas will be hereinafter. more fully described, illustrated in theaccompanying drawings and claimed.

In describing the invention in detail, reference Will be made to theaccompanyi drawing which shows a verticaltion' of the machineconstructed in acct, ance with this invention.

Referring more particularly to the drawings, 14 is a hollow verticalcylinder or drum, the upper end being closed by a fiat top; to the lowerend of 1% is attached an inverted hollow truncated cone 1?; to the apexof which is attached a short piece of cylindrical pipe 'Z is a piece ofcylindrical pipe held by the collar 6, on the top of said drum andvertically adjustable w i in said collar 6, the said pipe being insertedinto the drum 1% through. an opening near the center of the top; 4 apiece of c drical pipe connected tn the upper end the pipe 7. Thecylindrical pipe is inserted into the pipe lthrough an opening in theside of the pipe 4, pipe 5 is turned downward inside the pipe it 3 is apiece of cylindrical pipe connected the upper end of the pipe at; 3 isopen at the top and has an opening 2 in the side; 12

The operation of the machine is as follows laid su h as steam, air orwater 1S conpressure through pipe 5 pressure downward through the lercnr r is placed in the ducted by the pipe 21 into which sprays thewater l sand and mineral are 'i ii the pipe 3 and Enid from the pipe 5 d'nineral into the cup mineral into the merx e sand out over the eparticles of sand and separate as they pass Y under pressure.

cup. The reason that the lower edges of the ring 8 are turned inward atright an,-

gles is as tollowsz lt is found that in sands containing gold there areoften heavy sands such as iron or black sands. When the apforce of thefluid sand and mineral coming through the pipe- 7 sets the mercury inmotion flowing down:

Ward in the center ofthe cup .9 thence out-- ward to the sides of thecup thence upward andinward toward the center. The mercury rolls fromthe sides of the cup to the center in a convex curve leaving a spacebetween the mercury and the sides of the cup. The said heavy sands tendto gather in this space and being heavy will work downward into thebottom of the cup gradually forcing the mercury out of the cup. edges ofthe ring 8 prevent the said heavy the said space to the bottom of thesaid cup. These sands will then be carried upward with the other sandsand blown ofi" the surface of the The sand and any particles of mercuryand other mineral which are blown out of the cup 9 are collected by 13and 15 into the pan 35.. Power is applied to the cam-shaft 30 and thepan 3:") and the screen 26 are'set in motion, the pan being givena-lateral motion and the screen being held by metal straps rigidly fixedto the screen and to the bar 19 is given a lateral and ver'- ticalmotion, the vertical motion resulting.

from the resultant bending of the screen. This works the sand from thebottom-ct the pan Strand the mercury is allowed to settle. The motion ofthe screen really opens the sand so that the heavy mineral may fall Themercury a d gold or silver may then be separated by art.

The opening 2 at the upper side of the pipe 4 serves to admit air andthereby prevent the creation of any vacuum in the pipe silver and theThe bent lower the methods known to the which'would interfere With thepassage the stream of sand therethrough.

It will be observed that the lower edge q of the pipe 7 is above theupper edge of the cup 9 which leaves a free space through each. The sandmay be blown ofi" the surface of the mercury, this sand being collectedas explained by the casing'l l and nism to recover any precious metalvalues therein. s

From the foregoing description taken in connection with the accompanyingdrawings,,

the advantage of construction and of the method of operating thismachine will be readily apparent to those skilled in the art to whichthis invention appertains, and

been described together with various features of construction, thecombination and' arrangement of parts may be altered to suit practicalconditions provided such alterations are comprehended within the scopeof what is claimed.

I claim: I

An amalgama-tor comprising in combination a cup, an ai nalgamating bodytherein having a substantially adapted to distharge the sand or the likeagainst the surface of said body, the lower end of the pipe being ab ovethe up er edge of the cup whereby a free space wi 1 be left throughwhich the sand may be blown off and means for producing a fluid the pipeadapted to assist in projecting the particles agaihst the surface of theamalgamating .body,-a ring fitting around the edgehorizontal surface, apipe.

jet within of the cup having an inwardly turned flange adapted toprevent sand WOIkiI1g between the amalgamating body and the cup.

In witness whereof I have hereunto ailixed my signature in the presenceof two witnesses. I DANIEL DIVER.
